Some Matrix Inequalities in Multiport Network Connections
Tsuyoshi Andô, Fumio Kubo · Birkhäuser Basel eBooks · 1989
Connections of resistive multiport electrical networks give rise to several questions concerning comparisons among certain functions of impedance matrices of branch networks. In the present paper, some matrix inequalities, related to symmetric function means of an n-tuple of positive definite matrices, are proved to answer a part of the conjectures of Anderson, Morley and Trapp.
